TO ALL il-IOM I'l MAY CONCERN:

Be it known that I, CHARLES F. Wenen, of the city, county, and 'Stute of New York, have invented a new and improved Apparatus for Destroying Moths; and I do herel'y declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings forming part of this specification.

The object of this invention is to construct an apparatus wherein moths can be easily destroyed by means of het air, and wherein furniture and clothing are also prepared in such n manner that they are made incapable to serve again as food for moths.

lhe invention consists in the use of a spacious box, made of wood or any other suitable material, which is made air-tight, and provided wit-h a furnace and smoke pipe, the., so that the inside of the box may be heated to about 120 Fahrenheit. Furniture, clothing, or any other material containing moths, can be placed inte' the box, and is theu subjected to the heetfor from `three to ten hours, 'lhe heat is not ver/y intense, but as the box is air-tight, the moisture will be extracted from everything in the box, moths as well'as horse-hair or wool. The moths are soon killed by the extreme dryness, and the eggs are, from` the same cause, soon eompletely withered. The moisture iu the hair or wool of the clothes or furniture is also extracted, and the same are thereby made uin'it to serve as food for the moths, while the heat is not nearly strong enough to aifect in the least even the finest peliture ofthe furniture. The apparatus is furthermore so constructed that the heat can be decreased or increased at will, and that the interior of the box may be inspected at anytime, sothat the progress of the drying process may be watched. I n the annexed drawing my invention is illustrated- Figure 1 being a horizontal sectional view of my improved apparatus, taken in the line r 11:, tig. 2.

' Figure 2 is a vertical cross-section ofthe sume, taken on the line z/y, fig. l.

Figure 3 is a similar view, taken on the line z e, iig. l.

Similar marks of reference indicate corresponding parts.

A. represents a' box, made of wood or other suitable material, and lined on the inside wthsheet metal,

paper, or any other suitable material that will keep it air-tight. The box is Vlarge enough to be able to.hold

furniture, such as sofas, chairs, ete., which are laid upon a perforated false bottom, B, arranged within the box. The bottom D maybe made of bars, which are laid across the box A, as shownin the drawings. rl'he bottom should furthermore be so arranged as to be easily raised and lowered, so that the furniture may ne removed from or placed into the box with facility. Access to the inside of the box is had through a door, C, which, when locked, closes air-tight. `The upper surface, or any part. of it, or any part of one of the surfaces, may be made of glass, so as to facilitate the inspection otI the articles in the box. At any suitable partof the bottom ofthe box arranged a furnace or stove, D, which is enclosed in a metal box, E, as shown more particularly in iig; 'l`l'1rou ;h a door, l", access maybe had to the furnace. The pipes for conducting l(the smoke from the furnace to the outside lead -through the box A, and constitute two branches, G and H, one of which is very short and the other is of considerable length. 'lhe smoke can he directed either into the one er the other ofthese pipes by means of dempers o a, in the saine, which are operatori by rods Z: Ii, as shown. When a greater amount of heat is required in the hex A, the rear or one of the inner walls e ofthe box E, can belet down, being hinged, us shown in fig. 23, and then the whole heat of the furnace passes into the box A.. When but little heat is required, the door F is opened, and the heat escapes through the sanno.

I claim :is new, and desire to secure by Letters Patentl. An appara-tus for l'ler'vtroying moths, lhat is made und operating sul-)stantially :is heroin shown and described.

2. The device for regulatingl the heat in box A, consisting of the box E, pipes G und ll, dempers a a and c. and door F, all made and operating substa'uitially as herein shown and described. l

The use of air-tight boxes, in which racks or shelves B are arranged for holdingA furniture and clothing,

vc heat.

from which all the moisture is removed without an execs.
